Hi 6man,
 
I do not support the adoption.
CRH is not compatible with SRv6 and SRH.CRH has many associated control plane and data plane drafts. However, it is unclear on how these various pieces of work fit together. The working group need the proper understanding on the overall architecture before adoption this draft.
 
In my option,SRv6 compression should be done based on SRv6. Regarding SRv6 compression, I prefer G-SRv6 instead of CRH.
 
Therefore, right now is not a good timing to adopt CRH or even any other solution.
 
Best regards,

Zhao Feng
